In stock
Product Details

The TB-FF1-ENCORE-SELECT subwoofer enclosure with built-in amp rack is designed to fit under the rear seat of your 2009 - 2023 Ford F-150 SuperCrew Cab. This enclosure fits entirely under the rear seat, does not extend beyond the front or sides of the rear seat, and does not restrict seat movement. The subwoofers fire-down toward the floor, providing protection for the subwoofers and a nice loading effect for deep and powerful sounding bass that will elevate your listening experience. You can purchase just the enclosure on its own, or you can add subwoofers and/or an amplifier to receive a discount on the enclosure.

TruckBass Premier subwoofer enclosures include a laser-etched front accent that can be customized with your choice of logos. Black carpet upholstery is standard on the front and sides of the enclosure; however, a Katzkin upholstery upgrade is available for a premium touch. You can also add some excitement to the front of your enclosure by adding our optional LED lighting upgrade. You can choose between standard multi-color RGB LEDs, controlled by a wireless remote, or smartphone-controlled RGB LEDs, allowing you to select any solid color or choose from multiple chasing effects. Your design requests will be assembled by our production team using high-grade materials in our Rexburg, Idaho facility. You can typically expect a 4-6 week turnaround time from order placement to order shipment. Because this enclosure is built to your specifications, all sales are final.

Frequently Asked Questions

What is the warranty? " subwoofer enclosures are warranted to be free from defects and materials for a period of (1) year from the original date of purchase. Products purchased with your enclosure will be covered under the original manufacturer's warranty."
Does the subwoofer enclosure ship with the product in it? "No, to help keep the shipping weight down and mitigate potential damage to the subwoofer enclosure in transit, we ship the subwoofer enclosure separately from any other gear you may have purchased."
Does this come with everything I need to install it? "No, because every vehicle is unique based on the audio equipment installed from the factory or aftermarket, we suggest that you supply your own installation parts to accommodate your installation needs."
Can the lights stay one color? "Yes, regardless of whether you selected our standard or solid/chasing RGB LED upgrade, the lights can stay on one color if you select that mode."
Do you still offer colored accents? "No, in order to achieve a more cohesive look for our products and streamline the selection process, we now exclusively offer black accent acrylics. However, you can still have your logo(s) in any color you prefer by opting for our RGB LED upgrade."
How do I connect the LEDs? "If you've chosen our RGB LED upgrade, you'll need to wire the LED controller. We supply a power/ground pigtail that must be connected to the vehicle's power and ground, enabling the LED controller and lights to activate. We will soon post a video in this section, demonstrating how to connect the LED lights."
Can this enclosure be ported? "No, this specific enclosure is designed as a sealed enclosure. If you prefer a ported enclosure, you can select from our other available ported options."
Does this enclosure include an amp rack? "Yes, this enclosure has a built-in amp rack. The enclosure comes with a black carpet pressure-fit trim ring for the amplifier opening. This trim ring does not illuminate on SELECT and PREMIER models. If you would like your amp rack to include a laser-etched RGB LED accent with a Katzkin-wrapped trim ring, please consider checking out our ENCORE ELITE model."
Can I order this enclosure for different subwoofer configurations? "No, this enclosure is exclusively available for dual 10-inch subwoofer configurations."
How long will it take for me to get my enclosure? "The timeframe for this can vary based on our current workload. You can view our current turnaround times by clicking here."
Will this work with my floor mats? "TruckBass subwoofer enclosures are not specifically designed to accommodate floormats. However, this does not necessarily mean they won't fit or work with your floormats; we simply cannot guarantee their compatibility."
